Nucomm CHANNELMASTER TX7 - BAS Relocation Settings; Audio Sub-Carrier Frequency

Revision 1.03
Operation 5-17
5.11 BAS Relocation Settings
For our US clients, the ChannelMaster is designed so that, when properly config-
ured per the following guidelines, you will only need to change one setting on
one screen when it’s time to switch over to the “post-relocation” 2 GHz band
plan.
To preset the unit to allow a “one setting” switchover, there are two groups of set-
tings that must be made in advance: “AUDIO SUB-CARRIER FREQUENCY” and
“CHANNEL BANDWIDTH & BAND PLAN”. These are described below.
5.11.1 Audio Sub-Carrier Frequency
In this section, you set your “pre-relocation” and “post-relocation” Audio Sub-
Carrier (ASC) frequencies, so that when you make the switchover they will be
ready to go.
Start the ASC set-up procedure by making the following menu selections:
MENU>MODULATION>PARAMETER SETUP>FM>AUDIO
This brings up a screen similar to the one at right, with
the settings and selections as described below.
All ASC’s are modified in the same fashion. ASC#1 is
used as the example.
2(17)/7/13 This setting controls the frequency for the selected Sub-Carrier when op-
erating in the “pre-relocation” 2 GHz band (USA), as well as for all the
other frequency bands (i.e. 7 GHz or 13 GHz). The possible range for this
setting is 4.83 MHz to 8.5 MHz. (Refer to Section 5.2.1 - Changing Oper-
ating Frequency.)
2(12) 1-7 This setting controls the frequency for the selected Sub-Carrier when op-
erating in the “post-relocation” 2 GHz band (USA) on channels 1 through
7. The possible range for this setting is 4.83 MHz to 5.8 MHz. (Refer to
Section 5.2.1 - Changing Operating Frequency.)
2(12) 8-10 This setting controls the frequency for the selected Sub-Carrier when op-
erating in the “post-relocation” 2 GHz band (USA) on channels 8 through
10. The possible range for this setting is 4.83 MHz to
8.5 MHz. (Refer to Section 5.2.1 - Changing Operating Frequency.)

ASC1 ASC2 ASC3* ASC4*
2(17)/7/13 4.83 MHz 6.20 MHz 6.80 MHz 7.50 MHz
2(12) 1-7 4.83 MHz 5.80 MHz 6.80 MHz 7.50 MHz
2(12) 8-10 4.83 MHz 6.20 MHz 6.80 MHz 7.50 MHz
*NOTE: Due to bandwidth limitations, only two ASC’s can be active on the “post-
relocation” 2 GHz band-plan (US), regardless of how the unit is hardware configured.
